[0002] Food sealing is to seal food packaging bags or containers to prevent food from being affected by external contamination, oxidation, moisture, water and microorganisms, thereby extending the shelf life of food and maintaining its quality. When sealing plastic packaged food, heat sealing technology is generally used. Heat sealing is to expose the sealing part of the packaging material to high temperature and then seal it together through heat pressing or heat sealing strips. This method is suitable for most plastic materials, such as polyethylene (PE), polypropylene (PP), etc. Heat sealing has the advantages of fast and high efficiency, and can ensure good sealing performance.

[0003] When using the current food sealing machine, it is necessary to first place the food on the equipment, then adjust its position so that the sealing point is located at the bottom of the heat sealing knife, and then take out the food after sealing and repeat the operation. This will require stopping the machine for unloading after processing, and it does not have a continuous processing function, which reduces production efficiency and cannot quickly position the food, wasting human resources. It will also cause inaccurate sealing, affecting the appearance quality of the food leaving the factory. Utility Model Content
